John S. ★★★★★ Oct 12, 2026

Screwing this behind the FS-60CB objective basically gives me a second scope in one tube, and the field stays flat right to the edges. Star tests look clean, no color fringing even on the moon.

Amelia C. ★★★★★ Oct 10, 2026

Finally got this to turn my FS-60CB into an FS-60Q, and the 1.7x magnification is spot on for lunar close-ups. The threaded connection behind the objective screws on smoothly with no wobble.

Screwed this onto my FS-60CB and it basically turns the scope into an FS-60Q, which is exactly what I wanted. Stars that used to be soft blobs at high power now split cleanly, and there's no noticeable dimming. It's a permanent part of my kit now.
